Description
Technical Field
The utility model belongs to the technical field of detection device, especially, relate to a countersunk head screw axiality detects frock.
Background
In the field of manufacturing industry, in order to ensure the manufacturing quality of parts, each shape element characteristic of the parts needs to be detected to determine whether the produced parts are qualified, in actual work, because the parts are produced in large quantities, when a certain size element on the parts is detected, only qualitative measurement is needed to determine whether the parts are qualified, and repeated quantitative measurement on the size element is not needed, so that the labor intensity of inspectors is reduced The packing ring can not be completely accommodated in the countersunk hole, therefore, it is very important to carry out qualitative detection on the relative coaxiality between the countersunk hole and the threaded hole quickly, however, no instrument for qualitatively detecting the coaxiality between the countersunk hole and the threaded hole of the part exists in the prior art, generally, the judgment is carried out only by using quantitative detection instruments such as a vernier caliper to carry out measurement reading, on one hand, the working efficiency is not high, the labor intensity of detection personnel is increased, on the other hand, the measurement result data is easy to mix, so that the reliability of the measurement data is reduced, and therefore, a detection device for qualitatively detecting and judging whether the coaxiality between the countersunk hole and the threaded hole is qualified is urgently needed to be developed.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a countersunk head screw axiality detects frock.
The utility model discloses a following technical scheme can realize.
The utility model provides a countersunk head screw axiality detects frock, including dabber, axle sleeve and standard screw rod, the one end and the standard screw rod fixed connection of dabber, the dabber other end is outside to be extended, the axle sleeve suit in the spindle and dabber length is greater than axle sleeve length, be provided with standard shaft section on the axle sleeve outer peripheral face.
And the outer peripheral surface of the shaft sleeve is also provided with a handheld shaft section, and the outer diameter of the handheld shaft section is larger than that of the standard shaft section.
And the peripheral surface of the shaft sleeve is also provided with an observation port.

fig. 2 is a schematic view of the connection structure between the present invention and the tested part.
In the figure: 1-mandrel, 2-shaft sleeve, 3-standard screw, 4-tool withdrawal groove, 5-handle, 6-locking screw, 7-measured part, 11-connecting screw, 21-standard shaft section, 22-handheld shaft section and 23-observation opening.
Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in fig. 1 and 2, the utility model provides a countersunk head screw axiality detects frock, including dabber 1, axle sleeve 2 and standard screw rod 3, the one end and the 3 fixed connection of standard screw rod of dabber 1, the outside extension of the 1 other end of dabber, 2 suit of axle sleeve are in dabber 1 and dabber 1 length is greater than 2 lengths of axle sleeve, are provided with standard shaft section 21 on the 2 outer peripheral faces of axle sleeve.
Further, a handheld shaft section 22 is further arranged on the outer peripheral surface of the shaft sleeve 2, and the outer diameter of the handheld shaft section 22 is larger than that of the standard shaft section 21. The outer peripheral surface of the sleeve 2 is also provided with a viewing port 23. The projection of the observation port 23 on the axial section of the sleeve 2 is rectangular. In the process of detecting the coaxiality between the countersunk hole and the threaded hole, an operator can observe the screwing depth of the standard screw rod 3 through the observation port 23.
